Union Switch and Signal Co. Type "H-5" Dwarf Searchlights
Salisbury, Missouri
CP Bentley

This dwarf has an attached marker that displays Lunar for the following indications:
Diverging Clear: Lunar over green.
Diverging Approach: Lunar over yellow.
Diverging Advance Approach: Lunar over flashing yellow.

These signals were used by the Wabash on several lines, today not many dwarfs or high mast signals remain that display these indications. Some of the Union Switch and Signal dwarfs had cast ears in the cases of the H-5 to hold the marker, others such as below had metal mounts welded to them for the marker.
